I have been using POP Peeper for years and converted my Yahoo from classic Mail to new Mail about three weeks ago. Since then, I started using POP Peeper with IMAP with Oauth2 as suggested, which appears under https://login.yahoo.com/account/activity:
Apps connected to your account

POP Peeper
has access to Yahoo Mail

However, since 15 July, I've had no luck getting email notifications. I just downloaded the latest webmail module but I'm still getting the same error. I hope the following information from the "Error Overview" is helpful. Can someone offer advice as to what I need to do to get email notifications for Yahoo working in POP Peeper?

Code: Select all

--- Version ---
OS: Windows 10 
POP Peeper: 4.4.0.0
Webmail: 4.4.6.0
SSL: 1.0.2.11
IMAP: 4.4.0.0
SendMail: 4.4.0.0

Based on some searching of that error, there are quite a few reports of it, but no concrete information. The consensus I can find is that it may occur because of too many messages in the inbox? Do you know how many messages your account has?

Does POP Peeper display any messages for the account? That is, I'm wondering if POP Peeper is able to get "some" messages each time it tries -- until it encounters the error -- but each connection it's able to get more and more until it should eventually have all of them. Although, assuming you've left it alone to do its thing, it would seem this should have happened in the last 3 weeks.

It may also help if I could get a log from you -- email (support at esumsoft dot com) with the information requested above and I'll provide instructions for the log.
